True... true with a "but".
I have an external enclosure (for slim DVD readers) that uses an
additional USB port in order to be powered.
But you know what? I don't trust USB external enclosures that claim not
needing external power other than the common port or that use another USB
port to fetch it from there. They tend to lie... well, not "they" but USB
ports which do not always provide the full required voltage and then is
when your problems start: your DVD reader sporadically fails to write,
the USB hard disk is not being recognized or just is "sometimes", your
DVD reader has "hicups" when playing your favorite movie...
So yes, non-extra-powered USB devices work... when they work :-)
